Irwin Miller Administrative Assistant IM:jd Att. CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT CHANNEL PLACE TIDAL STRUCTURE AND STORM DRAIN EXTENSION (C-2367) ENVIRONMENTAL REVIEW --NOTICE OF DETERMINATION A preliminary environmental review of the project for a tidal • structure and storm drain extension in Channel Place in the City of Newport Beach has been performed. The review was conducted in accor- dance with the requirements of the California Environmental Quality Act of 1970, the State "Guidelines for Implementation of the California Environmental Quality Act of 1970," and the City's "Policies and Pro- cedures for Implementing the California Environmental Quality Act." The environmental statement has been reviewed and was approved by the City's Environmental Affairs Committee. As a result of the preliminary review, it has been determined that: 1. The project is approved. 2. The project will not have a significant effect on the environment. C• 3. An environmental impact report has not been prepared. A negative declaration has been prepared and is attached hereto. Benjamin B. Nolan Public Works Director AIM:jd 12/13/82 CHANNEL PLACE TIDAL STRUCTURE AND STORM DRAIN EXTENSION (C-2367) NEGATIVE DECLARATION BY PUBLIC WORKS DEPARTMENT CITY OF NEWPORT BEACH 1. PROJECT LOCATION: The project is located in Channel Place and Channel Park from 44th Street to The Rivo Alto. 2. PROJECT DESCRIPTION: A 264 foot long by 36-inch diameter storm drain will be constructed in Channel Place from 44th Street to a new tidal structure to be built at the northerly end of the Rivo Alto. The 8' square tidal structure will contain a 3' sluice gate with a motorized operator. The storm drain construction requires excavation, backfill, and surface restoration. 3. PROJECT GOALS: This project will relieve flooding of Balboa Boulevard and adjacent streets and private property caused by high tides or by storm. 4. EFFECT ON THE ENVIRONMENT: There will be no significant long-term irreversible or irretrievable effects on the environment. There will be minimal, acceptable short-term effects on the environment during construction. 5. BASIS FOR NEGATIVE DECLARATION: This project is consistent with the General Plan of the City of Newport Beach and could not have a significant effect on the environment. 6. INITIAL STUDY: The City of Newport Beach Public Works Department has prepared this Negative Declaration and its Initial Study in accordance with Article 7, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act of 1970. Copies of the Initial Study may be obtained from said department during normal business hours. Benjamin B. Nolan Public Works Director BBN:rb 12/10/82 CHANNEL PLACE TIDAL STRUCTURE AND STORM DRAIN EXTENSION (C-2367) INITIAL STUDY BY CITY OF NEWPORT BEACH PUBLIC WORKS DEPARTMENT A. CONFORMANCE WITH THE GENERAL PLAN The construction of these public works improvements will not conflict with the long-range planning program established by the General Plan of the City of Newport Beach. B. ENVIRONMENTAL CHECKLIST FORM An Environmental Checklist Form (attached) has been completed as a portion of this study. The following statements, referenced to questions presented on the checklist, explain all "yes" and "maybe" answers: 1 b. This project will require excavation, placement of back fill, compaction, and surface restoration along the 264 linear foot length of storm drain construction. 1 c. A 8' square by 5' high concrete tide gate structure will be built at the northerly end of the Rivo Alto. 3 b. Rate of surface runoff may increase since storm water, heretofore ponded in City streets during certain rainstorms, will be transported through an additional drain pipe to the Rivo Alto. 13 d. Construction of the proposal will relieve many instances of Balboa Boule- vard flooding and result in fewer detours of traffic from Balboa Boulevard. 14 a & Construction of the proposal will facilitate access for police and fire b. protection since many instances of flooding in Balboa Boulevard will be eliminated. 14 e. The net effect of construction of the proposal will be a reduction of man- power needed to maintain public facilities, including roads. Periodic storm drain maintenance and tide gate operation will be required; however, these effects are greatly exceeded by the manpower required for surveil- lance, detouring traffic, cleanup and street repair necessitated by the present street flooding conditions. 16 e. This project will improve storm drainage and prevent flooding of public and private property during high tide conditions. No new drainage systems will be required in the future as a result of the project. 12/10/82 1 ENVIRONMENTAL CHECKLIST FORM • I. Background 1. Name of Proponent en), o/New/oorf "toed( 2.
